These five color themes are designed for use with Emacs' built-in theme support in Emacs 24. However, they also work with older Emacs versions, in which case color-theme.el is required. Usage: If your Emacs has the `load-theme' command, you can use it to activate one of these themes programatically, or use `customize-themes' to select a theme interactively. Alternatively, or in older Emacs versions, use one of the provided wrapper commands to activate a theme: M-x color-theme-sanityinc-tomorrow-day M-x color-theme-sanityinc-tomorrow-night M-x color-theme-sanityinc-tomorrow-blue M-x color-theme-sanityinc-tomorrow-bright M-x color-theme-sanityinc-tomorrow-eighties
